Can using tap water instead of coolant in Pakistan lead to early radiator leakage in Alsvin?

Some Pakistani car owners use regular water instead of proper coolant. Could this be corroding the radiator internally and causing leaks?

Yes, this is a major contributor to radiator damage in Pakistan. Tap water:

Contains minerals and salts that corrode the inner radiator walls

Promotes rust and scaling in the cooling system

Reduces coolants ability to manage pressure and boiling point

Over time, this leads to internal weakening and leaks, especially in joints and welds.
